Be it known that'I, FRANKLBERNABD WER- sEL, Jr., a citizen of the United States of America, and a resident offLinwood road, near.

Hershel avenue,Mount Lookout, in the county of Hamilton and State of Ohio, (post-oflice address Nos. 318 to 320 West Pearl street, in the city of Cincinnati, county of Hamilton, and State of Ohio,) have invented an Improvement in Sofa-Beds; and I do hereby declare the following to be a full and eXact description thereof, reference being had to the accompanying drawings, making part of this specication.

My invention relates to combination sofas and beds; and it has for its object the improvement in the construction of such devices whereby they are simplified and rendered more ecient in action.

The novelty of my invention consists in the combination and subcombination of the parts,

as will be hereinafter set forth, and specifically pointed out in the claims.

Figure 1 is a transverse vertical section throughthe device when in its sofa form. Fig. 2 is a cross-section with the parts in the position assumed by them to form the bed. Fig.

3 is an enlarged broken section on line 3 3 of Fig. l. Fig. 4 is an enlarged view of link, partially in section. Fig. 5 is a perspective view of the link. Fig. 6 is a view showing lug G passing over the lug F2.

A represents a stationary base-frame having similar endv standards A2, (one only of which is shown,) aording'arms for the sofa, said end frames being preferably joined together simply by the bottom longitudinal members A3 A2, a lower back longitudinal member A5, and a top back longitudinal member A2. Cross-pieces A7 connect the ends of the members A3 A4 and are secured to the inner surface of the end standards at the lower margins.

B represents a movable seat-frame support, preferably of the boX form shown to adapt it to receive bedding and mounted to move with relation to the base-frame on rollers L t2 and casters a3. The base-frame is itself preferably mounted on casters to enable the whole 4 furniturepieceto be moved about the oor at Will-... .Tllasters 13x10 11.0.12 rest @nhe-'1100.13 when the device is in the sofa form, but the ycasters., as, rest on the ioor when the device is 1n thebed form. Four grooved rollers a CL2 areprovlded, two near each forward corner and two in the middle of the base-frame, said grooved roller being journaled in a stationary bearing o, secured to the member A3. A recess 02 in the member A2 serves to partially house the roller. For each of the four grooved rollers thus described two transversely-extending metallic T-forrn tracks L are provided on the lower side of the base of the support B. The forward ends of the T-form tracks have inclines, making that part of the T-form track Wider lthan the rear portion. In this wider portion of the T- form track are round recesses cl2. To the ends of the supporting-box B, a short distance in front of the rear corners of said boX, uprights E are fixed. To the up- 'per ends of these uprights are pivoted at points f the seat-frame D and back frame E,

.two rigid hinges f2 f3 being applied to saidV frames for the purpose. Links F serve automatically to lock the seat and back frames together when'the frames are at a given angle to each other, and the link F automatically unlocks said parts when a more acute angle is reached. Lugs G, rigidly secured to the hinge f2, engage and disengage with the lugs F2 on the inner side of links F. The pawls I operate by gravity. The pawls I prevent the lugs G from passing on the upper side ofthe vlugs F2 when the back frame is first raised from the horizontal to a vertical position. rl`he lugs 'G catch in the recesses H2 when the back frame E is raised to a vertical position;

but if the back frame E is still further turned on the pivot f it causes the lugs Gr to pass beyond the lugs F2, permitting the links F to fall slightly, thereby -permitting the lugs Gr to pass above the lugs F2 and sliding to the upper end of the link F, permitting the back frame E to be lowered to a horizontal polsition. When the movable seat-frame B is pushed back, so as to form a sofa, the incline passes over the pulley A2, thereby raising the outer side of the seat-frame from the floor,

and when the seat-frame B is pushed fully back the round recesses d2 catch on' the pulleys a2, holding it in position.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a sofa-bed, the combination of basebox, seat and back portions, standards rising from said box, Whereon said seat and back portions are independently pivoted, stationary lugs carried by one of said pivoted portions, engaging links carried by the other pivoted portions, said links automatically engaging and disengaging by gravity said lugs and locking said pivoted portions together when said pivoted portions assume a position substantially at right angles to each other they lock said pivoted members against independent pivotal movement and permit said pivoted portions to move together on a common pivot, substantially as described.

2. In a sofa-bed, a stationary base-frame provided with rollers journaled in bearings on the top of said base-frame, a seat-frame, transverse tracks attached to the lower side of a movable seat-frame, the front end of said tracks provided with inclines to raise the seatframe from the floor, half-round notches in the high portion of the transverse tracks to engage with the rollers attached to the baseframe, substantially as described.
